Specifically, air pump can be used for pressurization.

As shown in FIG. 3, FIG. 3 is a schematic view of the base.

The dirt receiving component 4 and the base 2 are detachably connected to each other.

The dirt receiving component 4 is detachably positioned on the bottom wall of the maintenance station, specifically, on the bottom wall of the cavity 22. The dirt receiving component 4 includes a first connection part, the base 2 includes a second connection part, the first connection part is engaged with the second connection part, such that the dirt receiving component 4 and the base 2 are detachably connected to each other. The first connection part can be a bulge, and the second connection part can be a groove, or vice versa, thereby achieving the cooperation. For example, the dirt receiving component 4 includes a bulge and the bottom wall defines a groove, such that the bulge can be detachably received in the groove. Optionally, the first connection part and the second connection part can be detachably connected to each other through the engagement of a sliding slot with a sliding rail. The sliding slot or the sliding rail can be positioned on the bottom wall or the sidewall of the cavity 22. The dirt receiving component 4 includes a sliding rail or a sliding slot engaging with the sliding slot or the sliding rail on the bottom wall or the sidewall of the cavity 22 to form a sliding pair. To facilitate the cleaning robot to climb into the cleaning container 3, the drop height between the front baffle plate 43 and the upper surface of the cleaning plate 32 is small. In some embodiments, the front baffle plate 43 is roughly flush with the upper surface of the cleaning plate 32.

In certain embodiments, the dirt receiving component 4 and the base 2 can form a sliding pair. The sliding pair can be of a sliding guide or a rolling guide, which is convenient for a user to pull out the dirt receiving component 4.

The base 2 includes slotted guides 21, and the slotted guides 21 are positioned at two opposite sides of the cavity 22. The slotted guides 21 can be L-shaped, T-shaped, or the like. In this embodiment, the slotted guides 21 are L-shaped, so as to match the guide rail 42 protruding upwards from the dirt receiving component 4. The slotted guides 21 on the base 2 and the guide rails 42 on the dirt receiving component 4 form sliding pairs in a sliding mode. Each of the slotted guides 21 includes a front end face and a rear end face, and the guide rail 42 can be extend through the front end face and the rear end face, so as to be detached from the slotted guide 21. Specifically, two ends of the slotted guide 21 are open for the insertion of the guide rail 42. The front end face is capable of facing the front baffle plate 43 of the dirt receiving component 4, and the rear end face is capable of facing the rear baffle plate 44 of the dirt receiving component 4. The front baffle plate 43, the rear baffle plate 44, and the guide rail 42 on the sidewall of the dirt receiving component 4 can cooperatively block the sewage from flowing out from the edge of the dirt receiving component 4. FIGS. 1-3 show the detailed structure of the dirt receiving component 4. To facilitate the cleaning robot to climb into the cleaning container 3, the drop height between the front baffle plate 43 and the upper surface of the cleaning plate 32 is small, in some embodiments, the front baffle plate 43 is roughly flush with the upper surface of the cleaning plate 32.

As shown in FIG. 1, FIG. 2, and FIG. 3.

The dirt receiving component 4 is plate-shaped, and a center part of the dirt receiving component 4 is concave to form the sewage collection chamber 41. Compared with a barrel-shaped dirt receiving component, the plate-shaped dirt receiving component 4 is lighter, occupies less space, and is easy to dismount. In some embodiments, the dirt receiving component 4 and the base 2 can form a sliding pair, and the dirt receiving component 4 includes a base plate, a guide rail 42, a front baffle plate 43, and a rear baffle plate 44.

The guide rail 42 is matching the slotted guide 21, the guide rail 42 protrudes upwards from the base plate and is configured to block the sewage from flowing out from a side edge of the base plate.

The front baffle plate 43 protrudes upwards from the base plate and is configured to block the sewage from flowing out from a front edge of the base plate.

The rear baffle plate 44 is positioned on the cleaning container 3 and abuts against the rear end face of the slotted guide 21.

when the dirt receiving component 4 slides into a use state where the base plate abuts against the rear baffle plate 44, the front baffle plate 43 abuts against the front end face, thereby forming the dirt receiving component 4 capable of blocking the sewage from flowing out from all the side edges of the base plate.

Both the guide rail 42 and the front baffle plate 43 protrude upwards from the base plate, thus preventing the sewage in the cleaning container 3 from splashing out of the dirt receiving component 4 or flowing to the bottom of the base 2 via the guide rail 42 when the sewage falls from the cleaning container 3 to the dirt receiving component 4, preventing the dirt from accumulating in the slotted guide 21, reducing the maintenance workload; in addition, the front baffle plate 43 can operate as a handle, which facilitates the detachment of the dirt receiving component 4. In other embodiments, the handles in other structures can be arranged to facilitate the detachment of the dirt receiving component 4. Owing to the existence of the rear baffle plate 44, when the dirt receiving component 4 slides into the use state where the base plate abuts against the rear baffle plate 44, the front baffle plate 43 abuts against the front end face, thereby forming the dirt receiving component 4 capable of blocking the sewage from flowing out from all the side edges of the base plate. Specifically, the front baffle plate 43, the rear baffle plate 44, the slotted guide 21 positioned on the sidewall of the base, the base plate, the guide rail 42 positioned on the base plate, the sidewalls where the guide rails 42 are positioned, and the cleaning plate 32 cooperatively define the sewage collection chamber 41 with a top opening. Because all the four sides of the base plate can block the sewage, the falling sewage all accumulates in the sewage collection chamber 41 without splashing outside. The sewage is discharged finally via the sewage discharger 5, no need to worry about the sewage flowing into the bottom of the base 2 or splashing on the floor, this improves the user experience.

In alterative embodiments, a waterproof seal is positioned between the front baffle plate 43 and the front end face of the slotted guide 21, between the rear baffle plate 44 and the rear end face of the slotted guide 21, and between the guide rail 42 and the slotted guide 21, thus preventing the sewage from leaking out of the sewage collection chamber 41. The waterproof seal can be a rubber gasket or the like.

In another embodiment, the dirt receiving component 4 can be detachably positioned on the lower part of the cleaning container 3 through a snap-fit connection, threaded connection, or the like.

As shown in FIGS. 4-5, FIG. 4 is a three-dimensional view of the dirt receiving component in a use state, and FIG. 5 is a three-dimensional view of the dirt receiving component in other states.

The arrangement of the sliding pair enables the sewage collection chamber 41 to be opened or closed like a drawer. The dirt receiving component 4 has the following two states:

when the dirt receiving component 4 slides from an original position as shown in FIG. 5 until the base plate abuts against the rear baffle plate 44, as shown in FIG. 4, the front baffle plate 43 abuts against the front end face, thereby forming the dirt receiving component 4 capable of blocking the sewage from flowing out from all the side edges of the base plate, in this state, the sewage collection chamber 41 is a sealed chamber with a top opening;

when the dirt receiving component 4 slides from an original position as shown in FIG. 4 until the base plate is separated from the rear baffle plate 44, as shown in FIG. 5, the dirt receiving component 4 continues sliding and completely separates from the base 2, at this time, the detached dirt receiving component 4 can be cleaned independently, and there is no need for the users to squat down or lift the whole maintenance station to clean the bottom of the cavity 22, which is very convenient. Moreover, the plate-shaped dirt receiving component 4 is lighter and easy to pull out compared with a barrel-shaped one.

In this embodiment, the dirt receiving component 4 operates as a transfer station of the sewage, and can be connected to the sewage discharger 5 to discharge the sewage. In another embodiment, the dirt receiving component 4 defines a bottom opening communicating with a sewer, or is positioned next to a sewer, or one end of the drainage pipe 52 communicates with the bottom opening, the other end of the drainage pipe 52 is connected to the swage tank.

As shown in FIG. 6, FIG. 6 is a schematic view of the sewage collection chamber according to another embodiment.

The sewage collection chamber 41 can be formed in the following connection relationship: the cleaning plate 32 can be directly superposed on the dirt deposition plate. The sewage collection chamber 41 is a chamber concave in the dirt deposition plat. In this way, the front baffle plate 43, the rear baffle plate 44, and the guide rail 42 protruding upwards from the base plate can be omitted, the sewage directly falls into the sewage collection chamber 41 via the drain holes 321 by gravity.

As shown in FIGS. 7-8, FIG. 7 is a schematic view of the dirt receiving component according to another embodiment, and FIG. 8 is a local enlarged view of part B in FIG. 7.

As shown in FIG. 1, the central part of the dirt receiving component 4 includes an ellipsoid or spherical groove; as shown in FIG. 7, the dirt receiving component 4 includes a bottom plate and a plurality of side plates connected to the bottom plate, and the bottom plate and the plurality of side plates cooperatively form a cavity structure. In this way, the dirt receiving component 4 has a larger storage space. The cross-section of the cavity structure can be rectangular, or the cavity structure is cone-shaped and other shapes, all of which defines a concave in the center thereof.

The front baffle plate 43 protrudes upwards, thus facilitating to draw out the dirt receiving component 4 for cleaning; the guide rail 42 also protrudes upwards, thus effectively preventing the sewage from entering the slotted guide 21 from a side of the slotted guide 21, further preventing the contamination from be generated in the slotted guide 21. When the guide rail 42 is not raised upwards and bent, the sewage can enter into the slotted guide 21 to produce dirt, and the narrow space in the slotted guide 21 is difficult to clean up, so it is easy to cause odor in the slotted guide 21. The guide rail 42 protruding upwards can effectively prevent the dirt and odor from be generated in the slotted guide 21.

As shown in FIG. 9, FIG. 9 is a local enlarged view of part A in FIG. 1.

The cleaning plate 32 can be flat in shape or a center of the cleaning plate 32 is concave. Optionally, the concave center of the cleaning plate 32 is the same as that of the dirt receiving component 4, or other concave structures such that the sewage can flow from the edge into the concave center, for example, the entire cleaning plate 32 is a curved panel with higher edge and lower middle part. In this embodiment, the cleaning plate 32 defines a plurality of drain holes 321 which form the sewage outlet. The plurality of drain holes 321 communicates with the sewage collection chamber 41. When the center of the dirt receiving component 4 is concave to form an ellipsoidal or spherical cavity, the plurality of drain holes 321 is preferably arranged above the ellipsoidal or spherical cavity vertically. The plurality of drain holes 321 can also be positioned at any position on the cleaning plate 32, as shown in FIG. 12. The connection mode of the cleaning plate 32 and the base 2 can be a fixed connection or movable connection. For example, the cleaning plate 32 can be detachably connected to the base through the engagement of a slide rail with d a slide slot.

The maintenance station further includes a clean water nozzle 62 positioned in the cleaning container 3 and facing the scrubbing component 11, the clean water nozzle 62 communicates with the water inlet pipe 61. The clean water nozzle 62 is positioned in the cleaning container 3, when in use, the clean water nozzle 62 faces the scrubbing component 11, the clean water from the water inlet pipe 61 is sprayed on the scrubbing component 11. The sewage generated during the cleaning flows naturally to the sewage collection chamber 41 through the drain holes 321 by gravity. FIG. 11 shows the detailed arrangement of the clean water nozzle 62.

The scrubbing component 11 of the cleaning robot 1 is in contact with the protrusion part 31 of the cleaning container 3. The rotating scrubbing component 11 is cleaned by the protrusion part 31.

In this embodiment, the protrusion part 31 is an integrated protrusion part 31 including a plurality of ribbed plates as shown in FIG. 9, and the plurality of ribbed plates is positioned at equal angles with the vertical straight line as the axis. In another embodiment, as shown in FIG. 10, the protrusion part 31 is a split-type structure including a plurality of ribbed plates. As a variant, the protrusion part 31 can be a protrusion part including a structure different from the ribbed plate structure, for example, can be a spherical or ellipsoidal protrusion part 31 protruding upwards as a whole.

The maintenance station further includes a drainage pipe 52. The drainage pipe 52 includes a detachable part 521 and a fixed part 522. The detachable part 521 communicates with the sewage collection chamber 41. An end of the fixed part 522 is detachably connected to the detachable part 521, and another end of the fixed part 522 is connected to the sewage tank 51. The detachable part 521 is detachably connected to the fixed part 522, when the drainage pipe 52 is blocked, the detachable part 521 is detached from the fixed part 522. Compared with a conventional structure that the drainage pipe 52 is directly connected to the sewage collection chamber 41 and the sewage discharge end, the detachable drainage pipe 52 of this embodiment of the present disclosure can easily clean and discharge the sediment. Specifically, the detachable part 521 is connected to the sewage collection chamber 41, the detachable part 521 runs through the bottom or the side of the sewage collection chamber. The detachable part 521 can be detachably connected to the sewage collection chamber 41 through a screw connection, a snap-fit connection or the like. The detachable part 521 can also directly extend into the sewage collection chamber 41 from the upper part of the dirt receiving component 4. In this way, the fixed mode of the detachable part 521 and the sewage collection chamber 41 can be snap-fit connection, muff-coupling or the like. For example, the detachable part 521 includes a hook, and the dirt receiving component 4 includes a hanging ring matching with the hook, and the hook is hung on the hanging ring for detachable fixed connection.

The maintenance station further includes a filtering structure positioned on the end of the detachable part 521 connected to the sewage collection chamber 41.

The ribbed plate structure of the protrusion part 31 can include a plurality of ribbed plates positioned at equiangular intervals with a vertical line as the axis, and the protrusion part 31 can include at least one ribbed plate structure. In the embodiment, the protrusion part 31 includes two ribbed plate structures configured to clean two scrubbing components 11 of the cleaning robot 1 correspondingly, each ribbed plate structure is an integrated structure, the plurality of ribbed plates can be made in one piece, which is convenient for installation. The rib plates in one piece can be fixed on the cleaning plate 32 through fixed connection such as threaded connection or the like. Optionally, the ribbed plate structure can be a split-type structure, the plurality of ribbed plates can be positioned at equiangular intervals with a vertical line as the axis and is independently mounted on the cleaning plate 32, the water inlet pipe 61 can be connected to more than one ribbed plate for spraying water. The ribbed plate connected to the water inlet pipe 61 is a hollow ribbed plate with through holes, and the water can be sprayed through the through-hole. Optionally, the water inlet pipe 61 and the rib plate can be connected to each other by such as a threaded connection or clamping connection between a shower head and a water pipe. In another embodiment, one scrubbing component 11 of the cleaning robot 1 can be cleaned by a plurality of ribbed plate structures, or two or more scrubbing components 11 of the cleaning robot 1 can be cleaned by one ribbed plate structure.

The cleaning plate 32 includes wheel fixing grooves, and the wheel fixing groove can be concave with respect to the surface of the cleaning plate 32, or can also be a fixing groove protruding upwards from the surface of the cleaning plate 32. In some embodiments, two wheel fixing grooves are positioned apart from each other. The distance between the two wheel fixing grooves corresponds to the distance between the left and right running wheels of the cleaning robot 1. After the cleaning robot 1 climbs up the cleaning plate 32, the running wheels are correspondingly clamped into the two wheel fixing grooves for positioning, so as to prevent the shaking or moving of the cleaning robot 1.

The drain holes 321 can be positioned equidistantly in the width and length directions, or positioned at equal angles with a vertical axis as the center, or positioned at equal angles in different radii, or positioned in a honeycomb fashion.

As shown in FIG. 11, FIG. 11 is a local enlarged view of part C of FIG. 10.

The clean water nozzle 62 is positioned in the cleaning container 3, for example, positioned over or below the scrubbing component 11 of the cleaning robot 1. The clean water nozzle 62 can extend out of the cleaning container 3, for example, extending from the sidewall, the top surface of the cleaning container 3, or from the cleaning plate 32. Specifically, the clean water nozzle 62 is positioned on the pipeline or sprayer of the cleaning container 3, the pipeline can be a threaded hose, and the spray angle and the distance between the clean water nozzle 62 and the scrubbing component 11 can be manually adjustable. In some embodiments, the clean water nozzle 62 extends from the cleaning plate 32. The clean water nozzle 62 can be positioned on the ribbed plates and faces up to the scrubbing component 11, which facilitates the integration of the water feeding mechanism 6 and the protrusion part 31 and makes the structure compact. The clean water nozzle 62 can also be positioned on the cleaning plate 32 and face the scrubbing component 11, and the cleaning plate 32 includes a water inlet chamber communicating with the water inlet pipe 61. The clean water nozzle 62 can be a plurality of through holes, which are equidistant in one direction or in different directions, or are positioned at an equal angle with a vertical line as the center. The plurality of through holes can be set in other honeycomb fashions.

Each ribbed plate includes a plurality of bumps 311. The cross-section of each ribbed plate is in curved shape and is convex in the middle of each ribbed plate. For example, the cross-section of each ribbed plate is semicircular or semielliptical. The curved shape makes the scrubbing component 11 be scrubbed more clean, and the through hole of the ribbed plate communicated with the water inlet pipe 61 cannot be completely blocked by the scrubbing component 11, thus solving a common issue that the clean water nozzle 62 of the protrusion part 31 with a flat top surface tends to be blocked by the scrubbing component 11. The bumps 311 can also be replaced by convex bars.

In another embodiment, the protrusion part 31 is rotatable. For example, a plurality of ribbed plates is fixed on a rotation shaft. When rotating, the protrusion part 31 can clean the non-rotating scrubbing component. For example, when the scrubbing component 11 of the cleaning robot is fixed at the bottom of the cleaning robot and cannot be rotated, the rotatable protrusion part 31 can be used for cleaning. In this embodiment, the clean water nozzle 62 can be arranged below or on the side of the protrusion part 31.

As shown in FIG. 2, FIG. 12 is a schematic view of the cleaning plate according to another embodiment.

As shown in FIG. 13, FIG. 13 shows a connection of the water inlet pipe and the magnetic valve.

The magnetic valve 63 is connected to the water inlet pipe 61. The magnetic valve 63 is configured to control the on or off of the water inlet pipe 61; the controller is electrically connected to the magnetic valve 63, and is configured to control the magnetic valve 63. One end of the water inlet pipe 61 is connected to the cleaning container 3, and the other end of the water inlet pipe 61 is connected to an external water source such as a tap. The pressurized water source in the tap can directly flow to the cleaning container 3 to clean the scrubbing component 11 without additional power source, which is energy-saving and environmentally friendly. The arrangement of the magnetic valve 63 and the controller facilitate the water inlet. The on-off between the water inlet pipe 61 and the cleaning container 3 can be directly controlled by the controller.

The maintenance station further includes two charging terminals 7. The two charging terminals 7 extend or are exposed out from the sidewall of the cleaning container 3, and the two charging terminals 7 corresponds to two charging electrodes of the cleaning robot 1 in position, such that the cleaning robot 1 can be charged through the charging terminals 7 while being cleaned. The positions of the charging terminals 7 and the wheel fixing grooves can be arranged according to the distance between the charging port and the running wheel of the cleaning robot 1, as so to simultaneously cleaning and charging the cleaning robot. The charging terminal 7 and the water feeding mechanism 6 can also be independently connected to independent switches to control the on or off thereof, so as to realize the single function of charging or cleaning.

In assembling the sewage collection chamber 41: the dirt receiving component 4 is inserted along the slotted guide 21 of the base 2 until the front baffle plate 43 of the dirt receiving component 4 is in contact with the front end face of the slotted guide 21. In this way, the front baffle plate 43, the rear baffle plate 44, the slotted guide 21 positioned on the sidewall of the base, the base plate, the guide rails 42 positioned on the base plate, the sidewalls where the guide rails 42 are positioned, and the cleaning plate 32 cooperatively form the sewage collection chamber 41 with the drain holes 321 over the sewage collection chamber 41.

When in use, the cleaning robot 1 is positioned in the cavity 22 of the base 2, and the running wheels of the cleaning robot 1 are received in the wheel fixing grooves. The scrubbing component 11 is in contact with the protrusion part 31, and the charging electrodes of the cleaning robot 1 contact with the charging terminals 7 on the base 2 to charge the cleaning robot. The scrubbing component 11 and the water feeding mechanism 6 are both turned on, the scrubbing component 11 begins to rotate. The clean water or the clean water mixed with the cleaning liquid flows to the clean water nozzle 62 via the water inlet pipe 61 and sprays to the scrubbing component 11 of the cleaning robot 1. The rotating scrubbing component 11 is scrubbed by the protrusion part 31, and the dirt is mixed with the clean water or the clean water mixed with the cleaning liquid to form sewage. The sewage flows into the sewage collection chamber 41 through the drain holes 321, and is discharged by the sewage discharger 5.

After use, the dirt receiving component 4 can be drawn out along the slotted guide 21 of the base 2 for cleaning, and the dirt in the dirt receiving component 4 will not remain at the bottom of the base 2.

Compared with the related arts, the maintenance station of the present disclosure includes the base 2, the cleaning container 3 is positioned on the base 2 for cleaning the scrubbing component 11 of the cleaning robot 1, and the dirt receiving component 4 including the sewage collection chamber 41 is positioned below the cleaning container 3. When in use, the sewage produced in the cleaning container 3 automatically flows into the sewage collection chamber 41 by gravity. The sewage collection chamber 41 is detachably positioned, so the dirt receiving component 4 can be detached off at any time to remove the accumulated dirt. Compared with a conventional structure where the sewage in the cleaning container 3 directly flows into the bottom of the base 2, the dirt deposits on the bottom of the base 2 is transferred to the dirt receiving component 4, so as to solve the problem that the dirt on the mop can easily stay at the bottom of the base 2. Thus, the dirt receiving component is easy to clean, and the users do not necessarily squat down or lift the entire maintenance station to clean the sewage collection chamber 41. The maintenance station of the present disclosure has the advantages of convenient cleaning, convenient maintenance, wide application range, no blockage of pipelines, energy saving and environmental friendliness.
